Post-Wildfire Watershed Emergency Response

CAL FIRE and the California Geological Survey continue to deploy Watershed Emergency Response Teams (WERTs) to recent burns located within state responsibility areas. Requests for WERT report information should be directed to CAL FIRE. [CAL FIRE by default provides WERT hazards evaluation reports and maps to affected communities, flood control managers, and emergency managers.]
